This little project from VR Urban (a group dedicated to creating interactive street art installations) seems to have flown under the radar since launching in January this year. Their digital installation integrates projection, laser guidance and SMS to create graffiti painted a digital slingshot. With a phone embedded into an over-sized slingshot, users simply type a message they’d like sent as part of their graffiti splat, and, guided by a laser, shoot that onto a wall that is being projected onto. The camera sitting above the projector tracks the laser point and then accurately projects the splat with message included onto the wall in real time. Very cool! (via Bas on Blogilvy)
